This commit changes the behaviour of the CMSIS-RTOS periodic timers to
have an initial timeout equal to the periodic timeout instead of
executing the callback function directly when calling the
osTimerStart(...); function.
This behavioural change is according to the CMSIS-RTOS specification.

Adding the ability to set and get pthread names by defining
some non-standard extension functions that were first
introduced by Glibc.
Similar to zephyr thread naming, these allow for thread
tracking and debugging even when using the more portable
posix API.
Though Glibc was the originator, the current POSIX functions
have return codes based on Oracle's adopted spec, so these
functions follow suit. The Oracle and Glibc function
prototypes match.

I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.
There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.
The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).
Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.
Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.
Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.
The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.
(Everything above is true for choices, menus, and comments as well.)
Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

The existing stack_analyze APIs had some problems:
1. Not properly namespaced
2. Accepted the stack object as a parameter, yet the stack object
does not contain the necessary information to get the associated
buffer region, the thread object is needed for this
3. Caused a crash on certain platforms that do not allow inspection
of unused stack space for the currently running thread
4. No user mode access
5. Separately passed in thread name
We deprecate these functions and add a new API
k_thread_stack_space_get() which addresses all of these issues.
A helper API log_stack_usage() also added which resembles
STACK_ANALYZE() in functionality.

The intention of disabling CONFIG_PRINTK is that all
invocations of it will compile to nothing, saving a lot
of runtime overhead and footprint since all the format
strings are completely dropped; instances of printk()
and related functions are no-ops.
However, some subsystems need snprintk() for string
processing, since the snprintf() implementations in even
minimal C library are too costly in text footprint or
stack usage for some applications. This processing is
required for the application to even function.
This patch continues to have disabling CONFIG_PRINTK to
cause the non snprintk functions to become no-ops, but
now we always compile the necessary bits for snprintk(),
relying on gc-sections to discard them if unused.
z_vprintk() is now unconditionally defined in the header
since it is not tied to any particular output sink and
is intended for users who know exactly what they are
doing (it's in zephyr private scope).

This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.
The refactoring strategy used in this commit is detailed in the issue
This commit introduces the following major changes:
1. Establish a clear boundary between private and public headers by
removing "kernel/include" and "arch/*/include" from the global
include paths. Ideally, only kernel/ and arch/*/ source files should
reference the headers in these directories. If these headers must be
used by a component, these include paths shall be manually added to
the CMakeLists.txt file of the component. This is intended to
discourage applications from including private kernel and arch
headers either knowingly and unknowingly.
- kernel/include/ (PRIVATE)
This directory contains the private headers that provide private
kernel definitions which should not be visible outside the kernel
and arch source code. All public kernel definitions must be added
to an appropriate header located under include/.
- arch/*/include/ (PRIVATE)
This directory contains the private headers that provide private
architecture-specific definitions which should not be visible
outside the arch and kernel source code. All public architecture-
specific definitions must be added to an appropriate header located
under include/arch/*/.
- include/ AND include/sys/ (PUBLIC)
This directory contains the public headers that provide public
kernel definitions which can be referenced by both kernel and
application code.
- include/arch/*/ (PUBLIC)
This directory contains the public headers that provide public
architecture-specific definitions which can be referenced by both
kernel and application code.
2. Split arch_interface.h into "kernel-to-arch interface" and "public
arch interface" divisions.
- kernel/include/kernel_arch_interface.h
* provides private "kernel-to-arch interface" definition.
* includes arch/*/include/kernel_arch_func.h to ensure that the
interface function implementations are always available.
* includes sys/arch_interface.h so that public arch interface
definitions are automatically included when including this file.
- arch/*/include/kernel_arch_func.h
* provides architecture-specific "kernel-to-arch interface"
implementation.
* only the functions that will be used in kernel and arch source
files are defined here.
- include/sys/arch_interface.h
* provides "public arch interface" definition.
* includes include/arch/arch_inlines.h to ensure that the
architecture-specific public inline interface function
implementations are always available.
- include/arch/arch_inlines.h
* includes architecture-specific arch_inlines.h in
include/arch/*/arch_inline.h.
- include/arch/*/arch_inline.h
* provides architecture-specific "public arch interface" inline
function implementation.
* supersedes include/sys/arch_inline.h.
3. Refactor kernel and the existing architecture implementations.
- Remove circular dependency of kernel and arch headers. The
following general rules should be observed:
* Never include any private headers from public headers
* Never include kernel_internal.h in kernel_arch_data.h
* Always include kernel_arch_data.h from kernel_arch_func.h
* Never include kernel.h from kernel_struct.h either directly or
indirectly. Only add the kernel structures that must be referenced
from public arch headers in this file.
- Relocate syscall_handler.h to include/ so it can be used in the
public code. This is necessary because many user-mode public codes
reference the functions defined in this header.
- Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
necessary to provide architecture-specific thread definition for
'struct k_thread' in kernel.h.
- Remove any private header dependencies from public headers using
the following methods:
* If dependency is not required, simply omit
* If dependency is required,
- Relocate a portion of the required dependencies from the
private header to an appropriate public header OR
- Relocate the required private header to make it public.

A double-free could cause very hard to find bugs when using the mempool
allocator as the same memory would end up being allocated twice
afterwards.
Now that bits in the block bitmap are cleared only when actually freeing
a block, we may simply ensure those bits are still set before clearing
them, effectively catching most double-free cases.
The alloc_bit_is_set() function is made static inline so that when
assertion checks are disabled the compiler won't complain about unused
code.

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'
I tweaked Kconfiglib a bit to find most of the stuff.
Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up

When small blocks are recombined to create a single block at a shallower
level, it is sufficient to remove those blocks from the free list. There
is no need to mark those small blocks as allocated in the bitmap.
This, in turn, removes the need to mark small blocks back as unallocated
when splitting up a big blocks as they'll already be so marked.
Only the first small block needs to be marked allocated and the
remaining blocks only need to be added to the free list.
This makes the code smaller and more efficient, especially since those
removed bit manipulations were located within loops.
